SHOE-DRYING ATTACHMENT FUR SOLE-SEWING MACHINES.

menses.

To all whom it may concern 7 Be it known that 1, JAMES BADLAT, a citizenof the United States, and resident of Des Moines, in the county 'of'Polkand State of Iowa, have invented a certain new and useful Shoe-DryingAttachment for Sole- Sewing Machines, of which the following is aspecification.

The object of my invention is to provide a shoe drying attachment forsoling ma-- chines of simple, durable and inexpensive construction.

A further object of my device is to provide a drying rack adapted to beoperated by the steam generated from the steam generator of sole sewingmachines. In this connection it should be mentioned that the sole sewingmachines, which are in common use in repair shops are provided withsteam generators, which are connected with the waxing device in themachine, so that the wax may be kept warm'and in a semi-fluid conditionto properly wax thread sewed through the soles. It should also beexplained that it is the custom to temper leather, which is formed intothe half soles, which are used for repairing. This tempering processconsists of soaking the leather in water, so that it becomessufiiciently pliable to be readily handled in the process of half solingshoes. When, however, the leather becomes so soaked it is desired tofinish off the edge of the sole and to black the edge, it is found thatthe wet leather has a tendency to fray, sothat it is impossible to put asmooth hard finish on the edge of it when one attempts to finish theedge of the sole, while it is still damp.

A further disadvantage results from the attempts to finish the edge ofthe sole during the time that it is still damp in that the damp leatherdamages the sand paper, which is used for buffers, so that almost threetimes as much sand paper is worn out where the buffers are used with thedamp leather as is the case where thebufi'ers are used with dry leather.My invention, therefore, consists of providing means for drying thesoles rapidly and conveniently as they are finished by the sole sewingmachine, so that by the time that the operator is ready to proceed withthe edge finishing. process the sole may be sufficiently dry to admit asmooth finish without excessive wear on the sand paper of the bufiers.

A further object of my invention is to Specification of Letters Patent.

provide a steam coil having a drying rack disposed thereabove and toconnect the steam coil with the steam pipes of the Wax heating system ofthe sewing machine whereby the drying rack may be operated withoutadditional expense. 7 lVith these and other objects in view, myinvention consists in the construction, arrangement and combination ofthe various parts of my device whereby the objects contemplated areattained, as hereinafter more fully set forth, pointed out in my claims,and illustrated in the accompanying drawmgs, in which 2 v Figure 1 showsa side elevation of my improved drying rack and its connections with thesole sewing machine and generator the outline of the former being shownin light.

lines, and

Fig. 2 is a top or plan view of the drying rack itself.

Referring to the accompanying drawings, I have used the referencenumeral 10 to indicate generally the base of a sole sewing ma-. chinehaving the sewing mechanism inclica-ted generally by the numeral 11. Asteam generator 12 is provided as a part of the equipment of thismachine and is operatively connected with the wax heating portionsthereof'by the pipes 13 and 14.

My invention consists in connecting to these pipes 13 and 1a a steamdrying rack, which is so placed that the shoes, which have been passedthrough the machine 11 may be conveniently thrown upon the drying rackto be dried while other shoes are being operated upon by the machine 11.The cross slats 21 and the longitudinal slats 20 must be formed fromsome non-conducting material such as wood in order that the leather maynot become burnt from the heat from the coil. Experience has shown thatwarmed metal will burn the leather very much more quickly than will woodor similar material, which does not conduct the heat readily, so thatthe drying frame should be composed of such a non-conduct ing materialand so shaped that shoes thrown thereupon will not be burned and thelife thereby taken from the leather.

My drying rack consists of a base 15, which as shown is secured to thefloor by a floor flange 16 and having at its upper end a'second floorflange 17. A U-shaped strap iron member 18 has its central portionsecured to the floor flange 17 and its ends Patented Nov. 1, 1919. vApplication filed September 4, 1917. Serial No. 189,496.

turned upwardly.) The ends of the member 18 support a horizontal dryingrack 19',

which consists of longitudinal slats 20 between which. extend aplurality of spaced parallel cross slats 21. A steam coil, which restsupon thecentral portion of the mem. ber 18, consist's of a plurality ofspaced parallel steam conducting pipes 22, which are suitably connectedtogether at their ends by meansoi elbows 23. A supply pipe 2% the dryingrack is installed to the right, of

and in line withthe machine 11, so that as soon "as the soles have beensewed to the shoes onthe machine 11, the shoe may be thrown onto therack where it will bedried from heat of the steam coil." It may be sug'gested in this connection that experience has demonstrated that the heatof approxi-. mately 125 degrees is best suited for the drying of theshoe leather as at this heat there is no tendency to burn the leatherandyet a sulhcient heat is produced to cause the il'noisture therein toevaporate. V The coils may besuggested that the further advantage hereindisclosed are substantially of such size relative to the capacity of thegenerator that they will permit very closely the desired degree of heatbut in order to insure this result I have provided .a control valve f28, which is disposed in the supply pipe of the steam coil. 7

By this means the heat supplied by the drying rack may be accuratelygaged. It

I resides from'this particular heat that the drying rack does notfurnish sufficient heat to materially change the temperature of the roomin which it may be installed, although it furnishes suificient heat todry the sole of shoe enough, so that it may be finished on the finishingmachine while the sole of the other shoe is being sewed on the sewingmachine. The sole of thesecond shoe may then be dried on the drying rackwhile the first shoe is being put through the finishing process, so thatthere is no necessity for delay due to the drying of the soles upon mydrying :rack, and so that they may be nicelyfinished at their edgeswithout undue wear on the sand paper of the buffers. It should also besuggested that my improved drying rack may be installed at a very slightcost and there is no operating expense connected therewith underordinarycircumstances, as the steam generator of the sole sewing ma chine doesnot costany more to run when operating the drying rack than when itssteam is merely directed into the wax heating mechanism' of a sewingmachine.

I claim as my invention:
